Abstract :To extent the rating range of current of IGBT , the parallel methods are presented in this paper. The fac2 tors led to current unbalances of each IGBT in parallel are analyzed and corresponding solutions are proposed. The effects are verified by simulation and experiments.
Key words :IGBT ; parallel ; on2state current balance ; dynamic current balance
